Do you want to modify Tiny Tina Wonderland's Saves, Tiny Tina Wonderland's Savefiles, or Tiny Tina Wonderland's Save Games? This is tech demo about running Python code in the browser, but you may use it to the modify the savefiles in Tiny Tina's Wonderlands. This was working as of TTWL v1.0.5 (2022-08-11 / DLC4).
Using Pyodide I managed to host the python commandline program ttwl-cli-saveedit on the web! So this means python is running in your browser. If you want to run it at home just run on a Linux or OSX computer:
pip3 install --user git+https://github.com/abramhindle/ttwl-cli-saveedit
More documentation for the commandline program is here: ttwl-cli-saveedit
This webpage provides a user interface for you to modify your Tiny Tina's Wonderlands (TTWL) save files. What can this save editor do?
Here's where I come off as a jerk: I will listen to actual coherent bug reports here. I am not very interested in feature requests. This is a technology demo. I will gladly accept pull requests. If you want something, then make it better, it is opensource, I just wanted to deploy python in the browser. Don't contact me about windows issues, or mac issues, or ask me where savefiles are stored. I don't know these things and I don't have any answers.
